Relvay makes a pregnancy pillow. We also tell you below when you should not buy one.
The short answer
The Newton Pregnancy Pillow is a 55 by 31 inch U pillow with a detachable arm, a foam and fiber core, and a washable cover. Its comfort and cooling claims are maker wording, not published tests.
- Good fit if you want full-body, two-sided support.
- Check first if your half of the bed is under 31 inches.
- Use the 30 days to test heat and turning at home.
Is the Newton pregnancy pillow worth a closer look?
Yes, if you want a large U pillow from a known brand with a removable cover. It is a full-body design, so the real question is whether it fits your bed and your nights, not whether it is well made.

I was 27 weeks and had two tabs open: the Newton pillow and a cheaper U pillow that looked almost the same. Theo was asleep. I had a tape measure in one hand and my phone in the other, kneeling on our queen bed like I was measuring for curtains.
My half was 30 inches. The pillow was 31. I sat there doing the math twice, as if the number would change.

Two numbers decide most of this: the pillow's width and your half of the mattress.
What exactly is the Newton Pregnancy Pillow?
It is a U-shaped pillow, 55 by 31 inches, with one arm that unzips so you can use it as a J or C shape. The core is a blend of memory foam and fiber clusters, 85 ounces of fill, inside a separate liner.

One boundary matters here. Newton is best known for crib mattresses. Anything said about those products, including how they are tested, is about a different product. This review only covers the adult pregnancy pillow.
Which Newton pillow claims are backed up?
The design facts are clear: shape, size, fill, care, foam label and return window. The comfort, cooling and support claims are the maker's description, with no test method shown on the page.
| Claim on the page | What backs it | What is missing | How you can check |
|---|---|---|---|
| "Cool Comfort", "No more hot and bothered!" | A cover described as breathable with a cotton surface | No temperature test or fabric percentage in the page text | Sleep on it on your warmest nights inside the 30 days |
| "Far more supportive than standard alternatives" | A full U shape and a foam blend core | What it was compared with, and how | Turn over twice in it. Does the bump side still hold? |
| "Eases discomfort", "relieve pressure points" | Design intent | Any study on this pillow | Treat it as comfort, not care. Pain goes to your midwife. |
| Organic cotton cover | Mentioned in an image description | Not stated in the page text we read | Ask for the cover's content label |
| CertiPUR-US foam | Named on the page | It covers the foam only, not the cover or comfort | Ask which part carries the label |
| 30-day money-back | Stated on the page | Condition rules and who pays return shipping | Ask before you order |
A claim you cannot test at home is a reason to keep the receipt, not a reason to skip the pillow.
Will a 31-inch-wide U pillow fit your bed?
On a king, easily. On a queen, it takes about your whole half. On a full, it is wider than your half, so it spills onto your partner's side.
| Bed (US width) | Your half | Newton U, 31 in wide |
|---|---|---|
| Full, 54 in | 27 in | 4 in wider than your half |
| Queen, 60 in | 30 in | About 1 in wider than your half |
| California king, 72 in | 36 in | Fits, 5 in to spare |
| King, 76 in | 38 in | Fits, 7 in to spare |
The J or C setup should take less room, but the page does not give its size. If you are planning to use it that way on a full or queen, ask for the measurement first.
Is the Newton pillow right for you? A fit checklist
It suits you if most of these are true. If two or more are false, look at a smaller design first.
- Your half of the bed is 31 inches or wider, or you will use the J or C setup.
- You want support on both sides of your body at once.
- You are happy to rest your head on part of the pillow or tuck your own pillow inside.
- You do not mind spot cleaning the insert. Only the cover goes in the machine.
- You can test it within 30 days, including on a warm night.
- It is in stock in time for the weeks you need it.
Nicole ticked four of six. Her half was an inch short and she runs hot. She did not want to find out on night twenty that both of those mattered.
What if you like the idea but not the size?
Then the trade is coverage for space. A U pillow holds you on both sides by surrounding you. Smaller setups support only the points that matter most, usually the bump, the back and the knees.
| You care most about | Look at |
|---|---|
| Support on every side, bed space is fine | A U pillow like the Newton |
| A full or queen bed you share | A C or J shape, or a compact set |
| Bump and back only | Two small wedges joined together, plus your own knee pillow |
| Spending nothing yet | Regular pillows under the bump, behind the back and between the knees |
Our pregnancy pillow buying checklist covers return terms and care for any model, and pregnancy pillows for a small bed goes deeper on space.
Nicole went with two wedges and kept her own pillow between her knees. The first Sunday, Theo woke up with his whole side of the bed, and she was still asleep next to him.
Frequently asked questions
How big is the Newton pregnancy pillow?
The product page lists 55 by 31 inches in the U setup. The size of the J or C setup, with the arm removed, is not given, so ask before ordering for a small bed.
Is the Newton pregnancy pillow cooling?
Newton describes the cover as breathable with a cotton surface and uses the words Cool Comfort. The page shows no temperature test, so treat it as a description and check it on your own warm nights.
Can you wash the Newton pregnancy pillow?
The cover is removable and machine washable on cold, tumble dry low. The insert is spot clean only and should air dry away from heat and sun.
What is inside the Newton pregnancy pillow?
A blend of memory foam and fiber clusters, 85 ounces in total, inside a separate liner. The page lists the foam as CertiPUR-US.
What is Newton's return policy for the pregnancy pillow?
The product page lists a 30-day money-back guarantee. Ask about condition rules and who pays return shipping before you order.
If the size is the problem: a smaller option
Relvay does not make a U pillow, so we cannot offer a Newton alternative in that shape. What we make is a 3-Piece set: two small wedges for the bump and the back, joined by a strap under you. It is the closest thing we sell for a bed where a 31-inch pillow does not fit.
Two wedges for bump and back, joined by a flat strap, about as wide as your torso. Keep a regular pillow between your knees. $79.99, 90-day returns.
Probably not for you if
- You want one pillow that wraps your head, both sides and knees.
- You want a cover sold as cooling. Ours is not.
- Your bed has room for a U and you like that feel.
Made for you if
- Your half of the bed is under 31 inches.
- You only need bump and back support and keep your own pillows.
- You want 90 days from delivery to decide.
